You hold space for one another. When one person is speaking, the other is doing nothing but listening: You are fully present for one another because you value what the other feels and thinks. You both value personal growth, and see how your relationship in particular is a tool to help you accomplish that. Your relationship preceded a significant shift in perspective.
You put feeling over fact. You talk more than you do anything else.
You appreciate what you have while you have it. You know who is better and handling each aspect of your lives together, and you trust one another to do just that.
